MdeModulePkg: Add definitions for ATA AHCI host controller PPI 

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=1409

This commit will add the definitions for ATA AHCI host controller PPI. The
purpose of the PPI in to provide:

* MMIO base address
* Controller identification information (DevicePath)

for ATA host controllers working under AHCI mode.
